Today is Pi day and since nobody brought us a pie, we'd thought we'd make our own, in chart form. The nerdy place the Internet is, it's all about celebrating March 14, or 3/14, the date that happens to correspond with the mathematical number π, or (roughly) 3.1415926535897932384626433832795028841971. But, given that the day is just about a numerical coincidence and also happens to involve a very pun-worthy word, there are only so many ways to go about doing it. We found about five ways, actually. And, as one might expect, many go for the food route.
